摘要：
A magneto-optical recording medium according to the present invention includes a reproducing layer having in-plane magnetization at room temperature and shifting to have perpendicular magnetization at temperatures at and above a critical temperature, a first in-plane magnetized layer having a Curie temperature in the vicinity of the critical temperature, a second in-plane magnetized layer having a Curie temperature higher than that of the first in-plane magnetized layer, and a recording layer made of a perpendicularly magnetized film, provided in that order.
